POVfER-DBIVEN STRIPPER OR HEADER HARVESTER.

Specification of Letters Patent.

Application filed January 19, 1918. Serial No. 212,661.

To all whom it may concern:

Be 1t known that I, Join; OLIVER BROOK, a British subject, and residentof -.H1llside, Curban, in the State of New South.

Wales, Commonwealth of Australia, have invented new and usefulImprovements in Power-Driven Stripper or Header Harpower drivenstripp'er or header harvesters andparticularly to the type which seversthe heads from standing crop and then.

threshes and winnows the grain. The object of the invention is toconstruct these machines in such a manner that a two-part rigidly framedcarriage borne on three wheels is provided to support the severalappliances for dealing with the cut or threaded heads, and to carry themotor e11- gine fromwhich'power is derived to propel the machine andwork the several grain harvesting appliances. I

The aforesaid appliances are arranged tandem fashion at the longitudinalcentral part of the machine framing, while the oomb,'-beaters andcutting appliances are arranged on detachable hinged adjustable frames,the gems being. so arranged that the main traveling wheels are propelledby the motor independently of the gearsv which drive the harvestingappliances, and further the'back part of'the machine frame which carriesthe motor is detachable and may be employed for other purposes.

By employing the aforesaid means for \propelling the traveling wheels,there is no .development of power by said main traveling wheels, thusthe machine is enabled to travel over soft or sandy soil without interfering with the speed of the harvesting machiner alsoby the travelingwheels transmitting no power to the harvesting machinery, it is not sosusceptible to the jerks or vibrationsoccasioned by the travelingIwheels coming in contact with obstructions or passing over uneven land.Clutch gears are provided to allow the traveling, wheels mg the comb,reel, reciprocating knife and to he stopped while the motor andharvesting machinery remain in motion. Again, by dismantling the grainheads severing, threshing and cleaning appliances, the machine can beused as a farm tractor.

To convert the header machine into a stripper harvester, the forwardpart carryendless conveyers is removed and a similar" hinged fra-mecarrying the comb, heaters and conveyers is arranged in its place, andfurther the comb of the stripper harvester may when required befurnished with rotary crop-head lifter. I

The invention will now be fully described aided by a reference to theaccompanying sheets of drawings in which'similar letters will indicatecorresponding parts,

The spindle of reel B has motionirn 'vartcd to it by sprocle ets connected with chain belt 0 whichderives motion from spindle O. The aforesaid longitudinal spindle N hasa knuckle joint a in it to allow for its radial movement during lheraising and lowering of the bomb frame.

The riddle box G is suspended on hang The rotary crop head lifter which.em-

ployed only on the'stripper harvester conin the arrangement.above thecomb of a spindle Q; carrying a series of bent arms (3 ol? the formshown in Fig, 6, said spindle lying just above the comb and at such aposition that the said arnisrevolve between the comb teeth to lift thewheat heads to a staiuliug or upright position, so that the enable thespindle Q to be adjusted at any desired height over the comb. The armsQ} are secured to an adjustable boss on said spindle and such boss mayhave either two or more'arms which are either curved, radial or ,bent asshown, each arm being of such a thickness to enable it to rotatein thecomb space. Further the said arms Q may be arranged to operate betweeneach second comb space or they may be arranged to lie at any otherregular distance apart. Each of the sway arms J is also supported by thebeater spindle, the ends of the latter passing through the arms.

The spindle Q, which carries said arms is driven by sprocket and chainbelting Q from a sprocket Q on aforesaid spindle U, or by any otherconvenient means itbeing necessary that the rotation of the. crop lifterbe greater than that of the traveling wheels, so that the arms willrevolve quicky enough to lift the heads up in front of the comb, andthen drop it on to the comb. Each arm boss is provided with a set screwQ? to lift the arms to be arranged in a spiral or straight line on theshaft or in a direction most suitable for dealing with the crop.

The. points of the comb teeth between which the arms revolve, arefurnished with spring guides Q? to direct the wheat heads to theadjoining spaces.

In 5 the adjustable'fore part of machine is shown arranged for astripper harvester, the heaters J being arranged behind the comhli andthe latter furnished with the rotary crop lifting arms Q while againbehind the heaters are the screw conveyers it shown driven by spur gearR from the aforesaid shaft 0, while the heaters J have motif] impartedto them. by a belt J from ,ley on end of threshcr spi lle E hon. isprovided on r gulate the travel of the maallow of the machine turdfurther friction clutch on with pulley s shit and is cainto gear torotate by freeln the clutch i he threshshaft ion clutch S for securingit to its shaft drum to be operated. Pulley or sproc m on shaft M is"also furnished with clutch to allow Sha it D employed.

of its being thrown in and out of gear, while the fan spindle isprovided with a free wheel clutch S to allow the fan to run itselfdownafter the machinery is stopped.

I do not make a claim for any particular type of differential gear orfriction clutch as it is obvious that any ofthe known types suitable forthe purposes stated may be employed in the herein described harvester,neither do 1 limit myself to any particular form of comb, conveyors,thresher or screening and winnowing appliancesas any suitable approvedtype of such devices maybe Having now described my invention what Iclaim as new and desire to secure by Letters Patent is:-
